You should add the same support to the ACPI matching.

 #ifdef CONFIG_OF
 static struct of_device_id goodix_of_match[] = {
-       { .compatible = "goodix,gt9110" },
-       { .compatible = "goodix,gt927" },
-       { .compatible = "goodix,gt9271" },
-       { .compatible = "goodix,gt928" },
-       { .compatible = "goodix,gt967" },
+       { .compatible = "goodix,gt911",  .data = (void *) 5 },
+       { .compatible = "goodix,gt9110", .data = (void *) 10 },

There's no need to add "10" for these tablets as it's already the 
GOODIX_MAX_CONTACTS value. Or you need to add it to every instance.

I would also like a link to the spec sheets in the commit message.

+       { .compatible = "goodix,gt9271", .data = (void *) 10 },
+       { .compatible = "goodix,gt928",  .data = (void *) 10 },
+       { .compatible = "goodix,gt967",  .data = (void *) 10 },
        { }
 };
